MUSCLE queries don't have a syntax that can specify database nodes of arbitrary depth. If you do need to keep track of nodes of arbitrarily deep nesting, here are some possible ways to work around that limitation: 1) Have each client that is uploading data to the database also upload a node containing information about how deep the data goes. The other clients could subscribe to this node, and update their own subscription strings appropriately whenever its contents indicate that the maximum node depth has changed. 2) Customize your muscle server to allow for some sort of special syntax or pattern that would support what you want to do. > Also, what if I want to say: > > */*/xyz/* > > without having to specify: > > */*/xyz/* > */*/xyz/*/* > */*/xyz/*/*/* > > etc. > > Will I need to modify the server=3F Yeah, I think you would have to. If you don't absolutely need an arbitrary deep nesting of nodes, I'd recommend just specifying a maximum supported node depth, and then all the clients can just post a finite set of query strings as in your example above.
